ABSTRACT:
Low inductance capacitors include electrodes that are arranged among dielectric layers and oriented such that the electrodes are substantially perpendicular to a mounting surface. Vertical electrodes are exposed along a device periphery to determine where termination lands are formed, defining a narrow and controlled spacing between the lands that is intended to reduce the current loop area, thus reducing the component inductance. Further reduction in current loop area and thus component equivalent series inductance (ESL) may be provided by interdigitated terminations. Terminations may be formed by various electroless plating techniques, and may be directly soldered to circuit board pads. Terminations may also be located on “ends” of the capacitors to enable electrical testing or to control solder fillet size and shape. Two-terminal devices may be formed as well as devices with multiple terminations on a given bottom (mounting) surface of the device. Terminations may also be formed on the top surface (opposite a designated mounting surface) and may be a mirror image, reverse-mirror image, or different shape relative to the bottom surface.
